- Step G Preparation of 4-(4-fluoro-1-naphthalenyl)-5-hydroxy-2,6-dimethyl-3(2H)-pyridazinone
- Step C Preparation of ethyl 2,5-dimethyl- ⁇ -oxobenzo[b]thiophene-3-acetate
- Ethyl 2,5-dimethyl- ⁇ -oxobenzo[b]thiophene-3-acetate (i.e. the product obtained in Example 2, step C) (30.25 g, 115 mmol) was dissolved in tetrahydrofuran and 1 N aqueous sodium hydroxide (150 mL, 150 mmol) was added. The reaction mixture was heated at 68° C. for 2 h. The reaction mixture was allowed to come to room temperature and concentrated under reduced pressure to provide a solid residue. The solid residue was diluted with water (100 mL) and acidified to pH 3 with 6 N hydrochloric acid, and extracted with dichloromethane (3 ⁇ 50 mL). The organic layer was collected, washed with water (2 ⁇ 20 mL), brine (20 mL), dried over MgSO 4 and filtered. The filtrate was concentrated under reduced pressure to provide the title compound as a light yellow solid (26 g).
- Step F Preparation of 4-(2,5-dimethylbenzo[b]thien-3-yl)-2,6-dimethyl-5-(2-pyridinylsulfonyl)-3(2H)-pyridazinone (Compound 2)
- the reaction mixture was diluted with water (50 mL) and extracted with dichloromethane (3 ⁇ 30 mL). The organic layer was further washed with water (2 ⁇ 20 mL) and brine (20 mL) and dried over MgSO 4 . The organic layer was filtered and concentrated under reduced pressure to provide a solid. The solid was further purified by silica gel column chromatography, eluting with a gradient of ethyl acetate in hexanes to provide the title compound as a light yellow solid (3.25 g).
- Step G Preparation of 4-(2,5-dimethylbenzo[b]thien-3-yl)-5-hydroxy-2,6-dimethyl-3(2H)-pyridazinone
- the aqueous layer was acidified to pH 3 with 1N aqueous hydrochloric acid and the mixture was extracted with dichloromethane (2 ⁇ 20 mL). The organic layer was collected, dried over MgSO 4 and concentrated under reduced pressure to provide a semi-solid product. This solid was further purified by silica gel column chromatography eluting with a gradient of ethyl acetate in hexanes to provide the title compound as an off white solid (0.70 g).

- Table 2 is constructed in the same manner except that the Row Heading “X is S, R 1 is Me and R 2 is Me.” is replaced with the Row Heading listed for Table 2 below (i.e. “X is S, R 1 is Me and R 2 is Me.”). Therefore the first entry in Table 2 is a compound of Formula 1 wherein X is S, R 1 is Me, R 2 is Me, (R 3 ) n is “-” (i.e. n is 0; no substitution with R 3 ) and R 4 is H. Tables 3 through 643 are constructed similarly.
